Our fourth annual compilation of the current year's most notable technology-related 25th anniversaries includes Microsoft's release of Windows 1.0, registration of the first dot-com domain names, the founding of AOL, the publication of Richard Stallman's GNU Manifesto, and the first fatal attack by the Unabomber. (With a couple of not-so-techie odd-balls tossed in for fun.) The press will revisit many of them one by one over the next 12 months, but here they are today, neatly assembled for your perusal.
